The technical field is as follows:

the utility model relates to a building materials field, concretely relates to multi-functional compound intergral template of gel polyurethane.

Background art:

under the global environmental problem, the 'resource saving and environment protection' becomes the basic national policy of the construction and development of China. The current building energy consumption of China is huge and the energy consumption is serious, and the situation is not in accordance with the basic principle and direction of 'saving energy and realizing sustainable development' in China. According to statistics, the building energy consumption of China accounts for about 24-30% of the total energy used in China, and is the first place of energy consumption; the heating energy consumption of the external wall of the building in China is 4-5 times that of the developed country with the similar climatic conditions, and the energy consumption of the unit building area is 2-3 times that of the developed country. China now becomes the second largest country for greenhouse gas emission in the world, and with the continuous improvement of people's lives, the proportion of building energy consumption and greenhouse gas emission will continue to increase. Under the condition, the building energy conservation has urgency and importance for the construction and economic development of China.

In the outer protective structure of building, the wall occupies the largest proportion of the building surface, so the heat loss of the wall is more people, so the wall heat preservation technology and energy-saving material become the main realization mode of building energy saving. The novel technology is used for carrying out high-level heat preservation and heat insulation on the building envelope structure, is a main measure for building energy conservation, can effectively reduce a large amount of energy loss caused by indoor and outdoor temperature difference in winter and summer, effectively solves the current situation of reducing high energy consumption of the building, and reduces greenhouse effect.

The heat preservation and energy conservation of the building in China starts late, and through research and practice for nearly two to thirty years, on the basis of referring to foreign technologies, the heat preservation technology of the building outer wall is greatly improved: on one hand, the new energy-saving technology of the outer wall is continuously researched and developed; on the other hand, the introduction and research and development of the external wall heat insulation material promote the energy conservation of the external wall to rise to a new height. However, the following disadvantages still exist in the aspect of wall insulation: (1) the heat insulation material has low heat insulation performance, for example, the heat conductivity of inorganic heat insulation materials is generally more than 0.05W/(mK), the heat insulation coefficient of organic heat insulation materials such as polystyrene boards and phenolic resin boards is generally more than 0.04W/(mK), and the high heat conductivity requires that the heat insulation material is made thicker, so that the consumption of the heat insulation material and the load of a building can be increased; (2) the thermal conductivity of the organic thermal insulation material is lower than that of the inorganic thermal insulation material, but the flame retardant property is generally poorer; (3) the heat-insulating layer and the decorative layer are easy to fall off, and the service life and the safety are affected.

Among a plurality of heat insulation materials, the polyurethane heat insulation material is one of the materials with better heat insulation performance, the heat conductivity can reach below 0.03W/(mK), but the flame retardant performance is poor, and the flame retardant performance can hardly reach B1 or A-grade flame retardant. At present, no polyurethane thermal insulation material with the flame retardant grade of more than B1 or A grade and the thermal conductivity of less than 0.023W/(mK) exists in the market, which is mainly caused by the structure of the existing material and the foaming process. If a better flame-retardant grade is achieved, the flame-retardant grade is difficult to achieve only by adding a flame retardant, the flame-retardant regulation and control of the structure of the polyurethane material are needed, and if the thermal conductivity is needed to be reduced, the structure and the principle of the aerogel need to be used for reference, and the cells are uniform as much as possible. However, at present, the problem becomes a bottleneck restricting the development of the industry, and the application of the polyurethane thermal insulation material in the building is also limited. If the problem can be broken through and a certain decorative effect is added, the application prospect in the heat preservation market is huge. In addition, with the development of times, the requirements on functional decoration of external walls are higher and higher, and besides heat preservation, self-cleaning, waterproof, antifogging, air purification, photo-thermal conversion to obtain heat energy, display function, power generation, thermal radiation regulation and control and the like.
